$100 if you fix it: Loss of speaker audio after BT connections

Hi all, I have had this bug in varying flavours with both the Wizard and now the Kaiser.
If I make a call via Bluetooth (certain devices only e.g. JVC in car stereo), after the call, all audio is lost on the device when using the speaker, e.g. no ringtones, no TomTom voice guidance. (Oddly the touchtone sounds on the phone dialler continue to work.)
Making another call via Bluetooth works fine and all audio is heard, but not if calling via the earpiece of the phone - all phone audio is still muted. A reboot is required. (Even after a reboot, sometimes all audio is muted, and 2 or 3 reboots are required.)
It is like Bluetooth is 'stealing' the audio from the phone's speaker (which is should), but not giving it back at the end, however turning off Bluetooth doesn't return it.
It happens with WM6.x on the TyTN II.
If you can fix it either via a workaround (reboot the audio service after every call?) or a direct fix (HTC are useless and have not emailed me back), I will pledge you $100 via PayPal. I am sure others will join me in pledging an amount also.

Yes. I've seen the same thing with the last stock Tilt ROM, too.

Same here. But is not happening very often.
The other issue for me is if I have A2DP enable and listening to music, then making a phone call will drop the A2DP connection and I have to reconnect A2DP again. It happens to both my JVC car unit and Sony HBH DS220.
I tried that w/ Dutty's WM6.0 and the latest 6.1 rom

I have the same issue, with bluetooth disconnects.

Just staying on-topic here (you can solve A2DP issues with A2DPToggle a great free app), has anyone found a solution to this Bluetooth loss of speaker audio issue, or a workaround to avoid it happening?
Rebooting the phone after every Bluetooth phone call is hardly what I consider a high-end smartphone to require.

Same here
What Radio's are you guys running? (Ignore my signature for the moment, been phoneless and away from here for a while and just getting back up to date )
Haz

My current radio is 1.64.08.21.
I have also tried 1.64.06.04.
Could we be closer to finding the problem? Does the Radio contain the Bluetooth stack?
Here are all available Radios:
http://wiki.xda-developers.com/index.php?pagename=Kaiser_Radio
I'm going to try 1.58.26.20 now. I suggest others try the other 1.5x variants and report back if any of them solve the bug.

Update: I am now offering $100 to anyone who can fix this - see 1st thread.
I have used Windows Mobile since the first ever SPV phone. This one issue is making me look seriously at abandoning that loyalty and getting a Blackberry. If I can fix this for $100 I could be tempted to stay however.

Have you tried BT Audio Toggle ? (found at http://pdaphonehome.com/forums/sams...luetooth-headset.html?perpage=20&pagenumber=1)
Maybe if this helps with your problem then a mortscript could be written to automatically run the utility after a phone call.

What bluetooth headset do you have? Have you tried other headsets or just the one you have? What version of 6.1 are you using?

Thanks, I'll give the audio toggle a go. Might need some help with Mortscript though
I am using the JVC KD-BT1 car stereo with Bluetooth in-car kit. However I can also lose audio on a clean boot even when not in the car, although that is very rare. When using it with the car stereo, it happens after almost every call.
I am running Sleuth's WM6.1 but the other people in this thread are using a variety of BT devices, ROMs, and HTC models.

Can anyone help with how to create a MortScript to run BTAudioOff.exe after each phone call?

Flash a NIKI radio. I had a similar issue with my JVC in-dash CD player and I just got all the radios and tried them all. All the NIKI radios seem to work a lot of the time, while some work and others don't.

Okay I tried this and before I even got in the car, chose to turn Bluetooth Audio off using the toggle. Since then I cannot recreate the issue! I am not having to toggle after every call, I only did it once and the problem won't come back!
Fingers crossed...

NP. 1 more thing. What do you mean all audio is lost? Do you mean that the auido goes through the bt device? Or just that there is no audio coming from either at all. If that's the case, then all you might have to do is go to Comm Manager>Settings>Bluetooth>JVC (or whatever you named it) and uncheck the Stereo sound and viola it should work unless you are not using A2DP >.> . I think it's either directing all sound to your bt device or trying to send sound to it but failing.

The issue is there is no audio coming from either the phone or the Bluetooth device. I hear the Bluetooth device disconnect, and its display shows that it has also.
I see no 'Stereo' option to untick for the JVC in its Bluetooth settings, only Hands-free and Wireless Stereo (already unticked).

No progress
Okay, this is seriously getting me down now It all sounded so promising. I have tried the following:
Flashed Niki Radio 1.58.21.23
Tried using Bluetooth Toggle - it seemed to work once when I turned BT off before connecting, but after a reboot the problem is back
Tried a HFP extension PM'd to me (thanks anyway - didn't help)
Made sure Bluetooth Stereo is unticked in the JVC's settings on the phone
I am not sure if the problem is worse when taking a call as TomTom is running.
Here is an interesting development which might help someone narrow down the cause:
I make a few calls, and as always audio is lost, even for phone calls sometimes.
Touchtones on the keypad are the only sound that the phone continues to emit itself. Everything else (TomTom, ringtones, etc.) is dead.
I then go into the JVC's A2DP mode and 'Connect'. The icon appears on the mobile's title bar, and I can hear phone audio through the car stereo.
I 'Disconnect' and the phone's audio is still lost.
What this tells us is that the phone is putting out sound, just not through the speaker.
If someone can write something that will reset the speaker driver after a call, my offer for $100 still stands.

Just to update this, the issue still exists with a clean install of HTC's new 2-May-08 WM6.1 ROM from their website. To***rs!

CJSnet,
Since we got the similar setup w/ exact the same issue (Att Tilt w/ JVC BT-1), I think the problem is basically Kaiser does not switch back to A2DP profile properly after headset profile from phone call. The same issue happens to my Sony HBH DS-220 stereo headset too.
I tried my Eten M600 w/ JVC BT-1 and does not see this problem

Play Music via Bluetooth "fixed"

This is my first, and only a minor, contribution to the forum; I've been a feeder up till now.
I bought a cheap bluetooth headset for my HD2 for use with my motorcycle satnav and also my HD2 - not that I want to take calls whilst I'm riding, but playing music would be a possibility. It was similar to this:
http://cgi.ebay.co.uk/Bluetooth-V2-...e_Phones_Bluetooth_Acc_ET?hash=item3efab16de4
I paired it with my satnav and could hear voice commands and music as expected. I then paired it with my HD2 and could only get calls, no music playing!!!
I tried looking for settings on the HD2 but nothing made any difference so I decided to look in the registry. After a while exploring I eventually found:
HKLM/software/widcomm/BTconfig/devices/
There were three devices paired (HD2, satnav and my car) so next I had to work out which one. I found that if you look at the nickname for each one, it's decoded into english by the Reg Editor (I use CERegistryEditor). Using trial and error I found that changing the setting "Hideconnections" from "0" to "1" did the trick. I can now hear music through the headset!!!
Well chuffed with myself!!!
PS Perform a soft reset after changing it to lock it in otherwise it resets to "0" after a disconnect.
OOPS! because I was looking for Bluetooth stuff I posted this in the wrong area, sorry!!! Maybe a moderator can correct please?

How bizarre it works by default for me......well done on the find though

Thanks...

It doesnt work for me, im using samsung mono bluetooth. I've tried many methods like btaudio bttoggle.... any help, thanks

All I can suggest is that - like I did - compare settings with something that does work. Maybe because you have a mono headset (mine is stereo) it's not capable of receiving music?

Hi
I could play music and receive system sound in my Jabra mono bluetooth earpiece if, in HD2, I go bluetooth->advance->Audio and check "play system sounds on remote hands-free device". However, after a phone call, the music and sound will be routed back to the phone speaker, though the earpiece is still connected (you can still make/receive phone calls through the earpiece).
The music and sound can only be routed to the earpiece again after a soft reset.
The other observation is that, if there is pause in between music or sound for a period of about 12 to 15 seconds, the HD2 will "suspend" the bluetooth transmission (beep in the earpiece) and resuming the music will cause the bluetooth transmission to be re-established (beep sound in earpiece). This is causing skipping of the first 1 to 2 second of the music / sound.
Have installed BTaudio V1.0. It is working on my HD2 and will keep the transmission constant and no skipping problem.
However, also needing soft reset after phone call.
Does any one has similar experience ? Is this earpiece/ head set related of is this HD2 related issue ?

No one has simialr experience ? Is there a thread on bluetooth related registry tweaks, I have been searching for it but don't seems to be able to find one. Any help will be appreciated.

I don't have that reg key at all! I have a dutch hd2 running stock 1.66. When I try to connect to a parrot party bluetooth stereo box this (most of the time) doesn't work. Once or twice I established a working connection but after trying multiple times with no luck I decided to find a fix for my problem. Now I try to edit my reg with this and it's not there!?

i paired the hd2 with the car kit parrot ck3100... leaving apart that it doesn't connect always... although i have checked in settings to play all phone sounds through BT it doesn't...
i think it's a BT problem of the hd2, or maybe all WM phones... 'cause ițve had issues like this before...
P.S. once it played the music thorugh the car kit... just like this...

A2DP Bluetooth Audio interrupts

Hi Guys,
i have this problem for a long time and didn't find anything about it in web or in xda forums.
I have a HTC Dream + HBH-IS 800 Sony Ericsson Headset.
When i listen to music via A2DP the connection is not very stable...
the connection interrupts very often for about 2 or 3 seconds, then works for about 3 seconds.
This only happens when i am outside, not in buildings. I this the reason is because of interferences. The connection gets better when i move the G1 into a specific orientation (upper side up) and don't turn my head to the right
On my old Windows mobile phone i played around with bitpool (=ratio between quality and connection stability by constant bitrate) settings... is there a possibility to get the connection more stable, when playing around with this setting?!
How can this setting be changed on android?
Further information:
-ROM Cyanogen 4.2.5 but same problem on stock ROM
-HTC Dream has been replaced one by a new device -> same problem
-Headset was never exchanged, but worked perfectly on my old Touch Pro with WM 6.1
Thanks for your help

There is a known issue on the Bluetooth stack and is suppose to be fixed in the Elclair 2.0 fix, the temporary work around is to first pair and connect then disconnect and reconnect it again i'm having to do that several times a day when i use my RocketFish bluetooth stereo headset. Hope that helps

thanks for this workaround, will try it tomorrow and will post if it works for me too

hmm, didnt really work for me... no change after pairing disconnecting and connecting again.
i wonder why this only happens outside, not in buildings... another frequencys which interferences maybe?!

Be sure to disable wifi.

Not trying to hi-jack your thread. If you want me to open another i will. However this is a BT question as well.
my G1 is set to connect to my stereo in my car. Pioneer BT head unit. I find that i have to manually tell it to connect every time i get in the car. When i had a blackberry before it would just connect every time on its own without me doing anything once i made the initial connection.
Any ideas?
thanks.

Worked on Dell Streak A1.6

I have Dell BH200 headset as well, and I have the same exact problem its like the audio stutters but when I first connect it its more stutter than music so you can barely even understand the music until after 30secs when it starts to normal out.
ATM im runnning Stock 1.6 for G1, im going to try Cyanogenmod 6.0 tomorrow and see if anything changes.
but everyday I go back and forth with my laptop and phone since my headphones run for atleast 3-4 days.

wow, finally someone having the same problem.
and even the same description of the connection issues.
I recently bought a orange SanFran and, as the device is fairly cheap, a nokia bh-504 along with it.
The connection isnt stable even when I put it in my breast pocket.
As soon as I move my head to the right, the streaming stops. Completely.
I can easily stop the music when holding my hand in front of the right earpiece.
so i will try the disconnect / connect again "workaround", but I don't think that will help.
I paired the same headset with my gf's netbook and I could walk through the whole apartment and the signal was stable even through up to 4 walls.
so no one here knows how to tweak BT settings in android?

Help with Bluetooth and Fresh 1.1

For some reason when my phone connects to a headset that supports both audio and phone the audio will not auto connect. I have to open the bluetooth options and hold down on the device i want to connect to then check the audio box.

sounds similar to the problem I'm having... I connect my phone via bluetooth to my car (Ford Sync) and I need to turn bluetooth off then on at least once (if not twice) for the car to recognize the phone.
I am getting so fustrated with this phone... Its been replaced twice (like replacing hardware is going to fix a software bug).
i really want to stay with an Android phone... maybe the Samsung Moment? it appears as if 2.x is now available (unofficially?) since Samsung released the Kernel source like they were supposed to.
TL

It worked before fresh 1.1 so maybe it was just a change in something.

I'm using the stock software and I have the problem so it is not freshrom

man we need an update HTC!!!!!!!

q1 almost over so we're that much closer to getting our official 2.1 update.

I've also got a bluetooth problem - would really appreciate any help you can offer.
I have a Tomtom and headphoned in my Bike Crash Helmet. I want to connect so I can hear music and phone calls through the phone in my helmet and also hear the TomTom.
The Tomtom connects to the Helmet, the phone connects to the Tomtom and I can get calls through the speakers via the Tomtom but music won't play (apart from an annoying second or two after dropping a call).
If I can get the phone to advertise headset features I could connect the Tomtom to the phone and the phone to the speakers (think that would work), otherwise I believe the Tomtom is not advertising media audio, only phone audio and don't expect I can change that.
Any thoughts...?
PS - Have tried the market headset app - unfortunately it doesn't fix the problem...

Issue using Car Handfree calling on MI5

Hi,
I've recently gotten the Mi5 and one issue that i have discovered is that when i connect it to the car hands free (Toyota Yaris with Toyota Touch 1) It doesn't let me speak and i can't hear the person on the other end.
There is a workaround where i would have to on the phone swap the output from Bluetooth - Handsfree - back to bluetooth and then it starts working again. I'm not sure its possible to replace the stock phone app on the device but although there is a work around it defeats the purpose of hands free calling if i have to do that while in the car!
Anyone have any ideas for a fix?
Thanks,

I did forget to mention that it worked fine with the Oneplus One it just appears to have this strange bug on the Mi5

Hi gavrai,
I have the same bluetooth issue. But when I answer the call using my phone I can talk using my car's audio without using the 'Bluetooth - Handsfree - back to bluetooth' method.
I am running the MIUI Global 7.2.4.0.0(MAACNDB) on my Mi5 connecting to a Volvo V40.
When I connect a HTC M7 or M8 to the car everything is working ok.
Hope someone has an idea

Maybe we should check the Xiaomi forums if there are any.....

I've got a mi5 and if I'm listening to music and then use the speaker of the phone, i.e. make a call, receive a call, make a voice recording to send via FB messenger or voice recording to send by text, then, when it switches back to music/podcast/bluetooth, the music/podcast starts skipping, like a record. I cannot figure out how to stop this glitch from happening. I've had one or two updates since I got the phone but this keeps happening and it's really frustrating. The only way I can stop the skipping is to turn off my bluetooth and then turn it back on. Any one have this issue or know how to fix it? Thanks
